Multiple Sessions in Oracle

I have a unique problem: I created an app in Delphi that is essentially a tracking program. It tracks certain items and the age. It also updates/inserts into the database. Now, when I log in to Oracle from within the Delphi app, everything is fine (I log in to Oracle as system and monitor V$Session); only one session is created. If I run this particular query from within the Delphi app, it creates 7 sessions in oracle. I've run the query in SQL Plus and only one session appears. Run within Delphi app, 7 sessions appear. We are running multi-threaded server and parallel server options o an Oracle 7.3.4 server (NT 4.0). I've created other Delphi apps that do not create this phenomenon. Here are some particlars:
- Query runs on a view of several tables (eqi-joined)
- View contains 2 longs
- Simple query only selects the fields
- App contains 2 query controls, one store procedure control, one database control, one table control and 3 datasources. I don't do multiple logins in a loop. I have noticed 7 sessions during logon and combo box population (via loop on table control). After it's finished, the other 6 sessions disappear. Another DBA and I watched as he killed every session, and nothing happened until he killed the true active session for the program. In fact here is the output from within SQL Plus:
USERNAME STATUS SID SERIAL# PROGRAM
